There are two assumptions that are usually in conflict with this method or style of improvement.
First, the author of the tip, trick, method, video, or book assumes that our BASIC golf skills are near perfect in-spite of our individual physical idiosyncrasies (ie. age, flexibility, bad or good knees? Bad or good ‘insert your individual imperfection‘)
Second, seasoned golfers, assuming their swing is based on individual foundations, often strive to swing like we ‘used to’ while trying out these new tips and in the process piling on more golf garbage in our heads. A new golfer often has a plethora of ‘suggestions’ from others that only confuses them.
